It should be remembered (or known) that often as time passes and researchers dig into the past that new and previously unknown original documents will come to life. This often changes perspective and interpretation immensely, as the previoulsy unknown material fills in blanks or clarifies unclear situations. Such may be the case with the aforementioned Alamo story. It isn't always easy to get the new information out to the general public as academics will argue it and demand proof-positive of it's validity. This isn't necessarily a bad thing, either, as it keeps nut jobs from making things up and say "Hey, look! I found this old journal and it says..." (though this still happens...a lot

).
This thread is really interesting to me right now as I am currently writing a paper which I intend to present at the 2006 Fur Trade Symposium in Chadron, NE. The paper is tentatively titled "What Did You Give the Indians for their Beads: Myths and Misconceptions of the Fur Trade by the Traveling Public".
One of the things I'm doing with the paper is examining where the myths and misconceptions come from. I've decided there are four main sources of myths and misconceptions (and this applies to all history): Hollywood, Popular Fiction, Poorly Research History and Bad Interpretation.
To quote from the rough draft of my paper (information copyright 2003 Robert W. Thomson):
Hollywood - Films and television shows are often where many people learn their "history". From
Dances with Wolves to
Dr. Quinn, Medicine Woman, from
The Far Horizon to
Little House on the Prairie, myths of the American and Canadian West are perpetuated over and over. The traveling public, watching these movies and shows at home, absorbs the information presented as fact. "You mean Hollywood lied to us?" is a question I was once asked in complete seriousness.
Popular Fiction - Historical novels and Westerns have been popular since Owen Wister's
The Virginian, or even since the era of the dime novel. However, as with films and television shows, these novels often change or embellish historical fact for the purposes of drama. Readers, even historians, can fall victim to believing the written word of a novel for historical fact. "I love history. I've read just about every book Louis Lamore wrote," was a statement made to an interpreter at Fort Union [Trading Post National Historic Site] a few years ago. Perhaps the worst example of popular fiction passing for history is Dr. Grace Hebbard's novel about Sacagawea. The information in Dr. Hebbard's novel is now often taught as fact in many grade school and high school American History classes.
Poorly Researched History - Even history books get things wrong. There are a variety of reason for this, ranging from sloppy or inadequate research to hidden agendss. While a text with inadequate research may be written with nothing bu the best of intentions, leaving out pertinent information will change the facts of the story and change how the story is perceived by readers. It should be noted that not every text with inadequate research is because the author was sloppy or lazy. It may very well be because pertinent information was not available at the time the book was researched and written. It is this reason that many classic "standards" of fur trade history are falling by the wayside. Hiram Chittenden's two-volume history,
The American Fur Trade in the Far West, was considered the standard introductory work for many, many years. But more comprehensive works by researchers with access to previously unavailable or unknown source material have corrected the inadvertant errors of Chittenden. Wood and Thiesen's
Early Fur Trade on the Northern Plains, Wishart's
Fur Trade of the American West and Sunder's
The Fur Trade on the Upper Missouri have become the new standard introductory works for the fur trade of the American West. By far, hidden agendas are much worse than inadequate research. Many writers today often set out with a preconceived notion of the fur trade and Indian/white relations, writing their book to espouse that notion and only quoting the source material that supports that notion. While Chittenden, DeVoto and Vestal can should still be read for their interpretation (though not necessarily their facts), the insidious nature of a historian with a hidden agenda creates a far worse picture. Their works can infect the public with a sense of false "correctness" about a given aspect of history. After all, a historian researched and wrote it; it MUST be true and correct. Such unprofessional works can also be harmful in another way. Over time, people may become jaded by such books and begin to think of all historians in the same bad light. "You historians just make things up as you go, anyway," was a comment made to a fellow Park Ranger once.
Bad Interpretation - Worse even than poorly researched history is bad interpretation. Public historians shoudl be the bastions of historical truth, interpreting the fur trade [or other historical topic] accuretly and objectively. However, poor research, agendas or even laziness often lead to myths and non-thruths being perpetuated [in museums and at historic sites]. Several times I have heard "That's not what I was told last time I was here." Not only does bad interpretation leave the traveling public with new misconceptions, or "confirm" existing misconceptions, but creates a conflict in them over whom to believe, this interpreter or the one they listened to ten years ago (or last week). This, too, can lead to the public becoming jaded and not believing or trusting what public historians/interpreters say anywhere or anytime.
